Early Girl Tomato in Zone 8B — Northern California

Early Girl Tomato is a fantastic choice for Northern California gardeners. Its quick maturity means you'll be enjoying homegrown tomatoes earlier than almost anyone else in the neighborhood! The flavor is classic tomato – perfect for sandwiches, salads, and sauces. Plus, the satisfaction of harvesting your own ripe tomatoes after such a short wait is hard to beat.

We know our Mediterranean climate comes with its own set of challenges, like dry summers and potential water restrictions. But with a little planning and attention, you can absolutely grow delicious Early Girl Tomatoes. Our long 269-day growing season gives you plenty of time to get a great harvest.

Starting your Early Girl Tomato seeds indoors is the way to go in our area, giving them a head start before going into the garden. Aim to sow your seeds late January through mid February. This gives them about six weeks to get a good start indoors before transplanting.

You'll need seed trays or small pots, a good seed-starting mix, and a warm, bright location. A heat mat underneath can help speed up germination. Once the seedlings emerge, make sure they get plenty of light – a grow light works great.

A tip I've found helpful: bottom watering. Set your seed trays in a shallow tray of water for a few minutes until the soil surface is moist. This encourages strong root growth. With our early springs here in NorCal, getting those seeds started indoors is key.

Transplant your Early Girl Tomato seedlings outdoors mid March through late April, once the risk of frost has passed. Before planting them in the ground, you'll need to harden them off. This means gradually exposing them to outdoor conditions for about a week. Start with an hour or two of shade, increasing the time each day.

When transplanting, space your plants 24-36 inches apart. This gives them room to grow and helps with air circulation. Even though our days are usually mild by this time, keep an eye out for unexpected late frosts.

Watering is crucial for Early Girl Tomatoes, especially in our dry Northern California summers. They need consistent moisture to produce those delicious early fruits. The goal is about 1-2 inches of water per week, depending on the weather.

Use the "finger test" – stick your finger into the soil about 2 inches deep. If it feels dry, it's time to water. During the hottest part of summer, you might need to water deeply every other day. In the cooler spring and fall, you can usually get away with watering less frequently. Water at the base of the plant, avoiding overhead watering, which can encourage fungal diseases in our low-humidity environment.

Signs of underwatering include wilting leaves and stunted growth. Overwatering can lead to yellowing leaves and root rot. A good layer of mulch around your plants will help retain moisture and keep the soil temperature even.

Early Girl Tomatoes are indeterminate, meaning they'll keep growing and producing fruit all season long. This means they need support to keep them off the ground. A standard 5-foot tomato cage works well, or you can use sturdy stakes.

Install the cage or stake at planting time to avoid damaging the roots later. As the plant grows, gently guide the stems through the cage or tie them to the stake with soft twine. This will keep the plant upright and prevent the fruit from touching the soil.

Pruning your Early Girl Tomatoes can help them ripen their fruit faster, which is especially beneficial in our climate. Focus on removing the suckers that grow in the "armpit" between the main stem and branches. These suckers will eventually produce their own stems, leaves, and fruit, but they'll also draw energy away from the main plant.

Remove the lower leaves as the plant grows, especially any that are touching the soil. This improves air circulation and reduces the risk of disease. Toward the end of the season, around late November, you can top the plant to encourage the remaining fruit to ripen before our first frost.

You can expect your first harvest of Early Girl Tomatoes early May through early July. This is one of the earliest-ripening varieties, so you'll be enjoying fresh tomatoes before most of your neighbors! The fruits are ready to harvest when they turn a deep red color and are slightly soft to the touch.

Gently twist the tomato from the vine, being careful not to damage the plant. Regular harvesting encourages continued production. As the first frost approaches in late November, harvest any remaining green tomatoes and bring them indoors to ripen. They'll ripen best in a single layer, not touching.

Here are some common problems you might encounter with Early Girl Tomatoes in Northern California:

Blossom End Rot

• What it looks like: A sunken, dark brown or black leathery patch on the bottom of the tomato.
• What causes it: Inconsistent watering, leading to calcium deficiency. Our dry summers can make this a real issue if you're not careful.
• How to fix/prevent it: Water consistently, especially during fruit development. Mulch heavily to maintain even soil moisture. Remove affected fruit – they won't recover.

Early Blight

• What it looks like: Brown spots with concentric rings on the lower leaves, spreading upward. Leaves yellow and drop.
• What causes it: A fungal disease that thrives in warm, humid conditions. Soil splash spreads the fungus to the lower leaves.
• How to fix/prevent it: Remove and destroy affected leaves. Mulch to prevent soil splash. Water at the base of the plant. Improve air circulation by spacing and pruning.

Hornworms

• What it looks like: Large sections of leaves stripped overnight. Big green caterpillars with white stripes. Dark droppings on leaves.
• What causes it: The larvae of hawk moths. They can defoliate a plant quickly.
• How to fix/prevent it: Handpick them (they're easy to spot). Bt spray is effective and organic. If you see hornworms with white cocoons on their backs, leave them – those are beneficial parasitic wasp eggs.

Cracking

• What it looks like: Splits in the tomato skin, either circles around the stem or lines radiating from it.
• What causes it: Heavy watering or rain after a dry spell. The fruit absorbs water too quickly.
• How to fix/prevent it: Water consistently. Mulch to maintain even moisture. Harvest ripe tomatoes promptly.

Northern California Specific Challenges: Our moderate-to-hot, dry summers and low humidity mean you need to be vigilant about watering and preventing blossom end rot and early blight. The key is consistent moisture and good air circulation.

Companion planting can help your Early Girl Tomatoes thrive. Basil is a great companion because it repels tomato hornworms and other pests. Carrots improve soil drainage and aeration, benefiting tomato roots. Parsley attracts beneficial insects that prey on tomato pests. French marigolds deter nematodes and other soil pests.

Avoid planting brassicas (like broccoli, cabbage, and kale) near tomatoes, as they can stunt tomato growth. Fennel inhibits the growth of many plants, including tomatoes. Corn can attract tomato pests like corn earworms.
